Matthew Perry has revealed one of his deepest, darkest secrets - what he believes is the funniest one-liner to be uttered by his character Chandler Bing.

The actor, 47, was on US breakfast show Good Morning America to promote his new series The Kennedy's After Camelot, when the interview turned to the subject of Friends - and he'd been asked to select his favourite ever gag.

Matthew was asked: "You were the king of the one-liner in Friends and we asked you what was your all time favourite, you chose one for us in a scene with Joey."
